Chemical Structure

4-Phenylphenanthrene CAS 4325-78-4 chemical structure

Description

The occurrence of 4-Phenylphenanthrene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Phenylphenanthrene (CAS 4325-78-4), molecular formula C20H14 and molecular weight 254.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a polycyclic aromatic system, 4-Phenylphenanthrene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 254.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
